EXTENSION-LAM P.

SPECIFICATION forming part of Letters Patent No. 324,793, dated August 18, 1885.

(No model.)

To all whom, it may concern.-

Be it known that I, HERMAN F. Janene, of Chicago, in the county of Cook and State of Illinois, have, invented certain new and useful Improvementsin ExtensionLamp Fixtures; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, and to the letters of reference marked thereon, which form part of this specification.

This invention relates to extension hanging lamps having counterbalancing weights, and comprises an improvement of the counterbalancing weight, the means for connecting it with and disconnecting it from the harp, means for supporting the shade, and means for separating the connecting shade and harp from the weight, all and severally as hereinafter set forth.

The drawing shows in front elevation and partial vertical section a hanging or extension lamp embodying my invention.

The harp is divided or two-part, and comprises the outer frame and the inner lighter frame, a, movable vertically within the outer frame in guides a, and having its upper ends, at, beveled or made inclined. This inner frame supports the fount b, and is provided with a rod or push piece, 7), extended vertically through the lower member of the outer frame, and freely movable in a vertical direction through said outer frame to move the inner frame. The counter-balancing weight is also divided or two-part, one part being integral with the crown c, and the other part, d, resting within the shade ring G, and packingrings 5 5 are interposed between the crown and part d, and between said latter part and the bottom of the shade-ring O, to overcome the jar of contact.

The lamp is suspended by chains 0 0, connected with the crown and shade ring in any suitable manner. The crown and shade-ring are connected detachably by means of hooks f, pivoted to the crown, with their active ends engaging notches in the weight (I, said hooks being held in position by means of springsf, attached to the crown an d engaging the squared ends of said hooks.

When the lamp is to be lowered, the inner frame, a, is moved vertically, by means of the pushpiece 11, until its beveled ends a come in contact with the lower beveled ends of the hooks f and force said hooks out of engagement with the weight (1, when said weight (1 and all of the parts of the lamp below it are movable from the crown. The shade-ring is provided with the upwardly-flaring rim I, within which rests the part (1 of the eounterbalancing weight, and said ring is also provided with a downwardlyprojecting flange, J, provided with set-screws for use in attaching the shade F, the said shade being further surrounded and protected, but not supported, at its lower end in a flange ring, I), supported on lateral projections E from the outer frame of the harp. The said ring D may be provided with such ornamentsas prisms, for example-as are commonly applied to lamps, substantially as indicated.

The outer frame of the harp is detaehably connected with the shade'ring O by its upper ends entering sccketed projections H from the lower side of the shade-ring, and connected therewith by spring-hooks g, engaging lugs It on said frame.

By disconnecting the springhooksg from the lugs on the arms of the outer harp the said harp, including both its frames, the at tached lamp, and its immediate appurtenances,

may be bodily removed from the shade-ring and weight.

, In another application for Letters Patent for hanging lamps, filed by me Detober 18,

1883, Serial No. 109,389, I have shown a harp provided with a shade-ring by which the shade is connected, the said harp, with its attached shade, being detachable from the crown bodily, so as to carry away from the crown and its attached parts not only the harp and the lamp, butalso the shade, in these respects differing from the presentinvention, wherein, as stated, the shade remains with the suspended parts when the harp is disconnected.

The combined weight of the parts 0 and d of the counterbalancing weight will be about equal to that of the harp, fount, and appurtenances, so that the latter may be lowered or raised to any desired point and caused to remain in such position till positively moved. \Vhen the harp is to be lowered for any pur- Ice parts are to be connected again, the inner frame, a, is brought down into its lowermost position, so as to free its beveled ends from contact with the beveled ends of the hooks f, to permit them to spring into the notches in I 5 the part (Z of the counterbalancing weight.

As will be seen, the shade is held by its setscrews between the ring J and the projections H, and is thus securely held at its upper end, while its lower end rests in the ring D. I do not limit myself to the exact details described.

as they may be materially changed without departing from the spirit of my invention.

I do not claim, in a hanging-lamp fixture, the combination of a shade-ring constructed 2 with slots, and the frame or harp constructed with corresponding flanges to engage with said slots.

I do not herein broadly claim the combination, with a hanging-lamp frame or harp, of c spring-clasps detachably engaging the same with the supporting memberynor do I claim the harp of a hanging lamp having tongues, combined with a suspending ring, and springclasps depending therefrom and detachably engaging the said tongues, the same being claimed in ,my application N 0. 109,389, filed October 18, 1883.

What I claim is- -1. ln an extension hanging lamp, the com- 0 bination, with a supporting-chain, of a counterbalancing weight made in two partsdetachably connected by spring-catches, a support for the lower part of said weight, and the harp composed of an outer and an inner frame, the latter movable vertically to dis- /connect the two parts of the weight to permit the lowering of the harp, substantially as set forth.

2. In an extension hanging lamp, the com- 0 bination, with the supportingchain, of'a weight made in two parts detachably connected by spring-catches, a shade-ring to support one part of said weight, and the harp made in two parts, one within the other, the

5 5 one part being movable vertically, as and for the purpose set forth.

3. In an extension hanging lamp, the combination, with the supporting-chain, of the two-part counterbalaneing weight, springcatches to connect said two parts, a shadering to support one of said parts, the harp composed of an inner and outer frame, the former movable vertically within the latter and having beveled ends to engage the springcatehes, and the push-piece to operate said inner frame, substantially as described.

4. In an extension hanging lamp, the combination, with the supporting-chain, of the divided counterbalanoing weight, the spring catches for detachably connecting the parts of said weight, a shade-ring to support the lower part of the weight, the harp detachably connected to said shade-ring and provided with an inner frame movable vertically to disconnect the parts of the weight, substantially as described.

5. In an extension hanging lamp, the combination of the supporting-chain and counterbalancing weight, and shade-ring having socketed downward projections, the harp having ends to enter said projections and pro vided with lugs, and spring-catches to cooperate with said lugs to connect and disconnect the shade-ring and harp, substantially as set forth;

6. In an extension hanging lamp, the combination, with a harp having lateral brackets, of a ring supported on said brackets to receive the lower end of the shade, and a shade-ring having sockets to receive the harp, and having a downwardly-pro ecting rim provided with set-screws, between which rim and the harp-sockets the upper end of the shade is socured by said screws, substantially as set forth.

7.. In an extension hanging lamp, the combination, with the supporting-chain, the divided weight, and the shade-ring, of thepack ing-rings interposed between the shade-ring and the divided weight, substantially as and for the purpose described.

8. An extension-lamp fixture provided with supporting devices for the neck of the shade, and a ring-which surrounds and protects the lower edge of the shade, but is not supported thereby.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

HERMAN F. JAEGER.
